His team has more work left to do to study how this new mechanism of optical gain works at different temperatures — and how to use it to create the nanolasers purposefully.
“The next step is to design lasers that can operate specifically using the new mechanisms of optical gain,” Ning said.
With the physics foundations laid, they could eventually be applied to create new nanolasers that could change the future of supercomputing and data centers.
“The long-term dream is to combine lasers and electronic devices in a single integrated platform, to enable a supercomputer or data center on a chip,” Ning said. “For such future applications, our present semiconductor lasers are still too large to be integrated with electronic devices.”
